Well I have no problem with the NMs but to me personally the allure to the Notorious Monsters in FFXI was the fact that they were so difficult to find, claim and kill and then get the drop - I must have killed Jaggedy-eared Jack about a 100 times without a drop, so I absolutely hated that aspect of it but I loved randomly running around a region and OOHHHH MAAA GOOOODDD Leaping Lizzy!! and your heart races a little (until you kill it and don't get the drop). So anyway, I think that completely goes out the window with small repop timers...if they're commonplace, they're no fun, they're simply just another mob.
